Blake's Newly Grey Tooth

So Blake fell when we were at the Tokyo airport and hit his mouth on the tile floor, I thought it would be alright cause it hadn't turned colors and was not loose or anything like that. Well about a week ago it started turning grey. We have a pediatric dentist in our stake here so Noah had him look at it on Sunday and he said that as long as he doesn't get a white spot on his gum's above the tooth that it should be fine and they don't want to pull teeth when they are young because it will leave a gap that his other teeth will want to fill in and then when his adult teeth come in it can cause problems. So for the next who knows how long Blake will have a grey tooth right in front of his mouth for the whole world to see..
